unable to access loop workspace

Hi All,

One of our users is a rehire and is currently experiencing issues accessing a Microsoft Loop workspace. The user shared the Loop workspace display name (for example, myteam1) along with the URL. The URL resembles the following:

[Moderator note: Personally Identifiable Information removed]

As a Global Administrator, I attempted to locate the workspace using the display name (myteam1), but I was unable to find it in Active Containers under Sharepoint Embedded. I also tried accessing the content storage URL directly:

[Moderator note: Personally Identifiable Information removed]

However, it returns HTTP 404 – Not Found. In SharePoint Online, when users experience access issues for sharepoint site, we can often navigate to: /_layouts/15/people.aspx?MembershipGroupId=0 and remove the affected user from the site's permissions, then ask the sharepoint owner to share the site again.

My questions are:

    1. Is it possible to identify the underlying Microsoft Loop workspace or SharePoint Embedded content container associated with the container ID [Moderator note: Personally Identifiable Information removed] ? I am unable to locate the workspace by searching for the display name (myteam1) in Active Containers, and I am unsure whether this is the main Loop workspace or an individual Loop page/component.
    2. Can administrators manage membership or permissions for Loop workspaces in a manner similar to SharePoint sites? For example, is there an administrative interface or PowerShell method to view and manage members?
    3. Is there an equivalent method to remove and re-add a rehired user to a Loop workspace when the user is unable to access it? In SharePoint Online, we can remove the user from site permissions and ask the owner to share the site again. Is a similar approach available for Loop workspaces?
    4. Has anyone encountered Microsoft Loop access issues for rehired users, particularly in cases where the user account was recreated, restored, or rehydrated after termination and rehire?

Hello @Glenn Maxwell

As this is a complicated issue, I would like to first summarize it to ensure we are addressing it in the right direction:

  • You have a rehired user who is unable to access a Microsoft Loop workspace. The user has provided the workspace display name (e.g., myteam1) along with a Loop URL pointing to a SharePoint Embedded content container (CSP ID).
  • From your checks as a Global Administrator, you were unable to locate the workspace using the display name in Active Containers (SharePoint Embedded). Additionally, when attempting to access the associated /contentstorage URL directly, it returns an HTTP 404 - Not Found error.
  • You would like to confirm how to identify the corresponding Loop workspace or container, how access is managed, and whether there is an equivalent method to reassign permissions for the user similar to the approach used in SharePoint Online.

Along the way, I will clarify each of your questions with key points and include Microsoft documentation for your reference, so you can review and assess how to apply it to your current scenario.

1/ Can the Loop workspace be identified from the CSP container ID?

Yes, however, this cannot be done via display name search.

Microsoft Loop workspaces are stored as SharePoint Embedded containers (CSP ID). To locate the corresponding workspace, you would need to use PowerShell (Get-SPOContainer) rather than relying on the Admin Center UI.

Admins can list and find containers using:

Get-SPOContainer (PowerShell)

2/ Can admins manage Loop workspace membership like SharePoint sites?

Partially, but the model is different.

  • Loop workspaces are managed at the container level, not via SharePoint site permissions:
  • No classic SharePoint permission page

Only 2 roles available:

  • Owner and Editor
  • Administrators can manage access via:
    • SharePoint Admin Center (Containers)
    • PowerShell

3/ Remove and re-add a rehired user

Yes, this is the recommended approach.

Since access is based on workspace/container membership, you can:

  • Remove the user from the workspace/container
  • Re-invite the user

This is the closest equivalent to the SharePoint “remove and re-share” method.

4/ Rehired user access scenario

This behavior can occur.

Access to Loop depends on:

  • The current user account
  • Existing workspace membership

If the account has changed during rehire, the user may need to be added again to regain access.

If you still need my assistance, please come back with screenshots or any additional details so I can review it again and see if there’s anything more I can help you with.
